根据田陈煤矿微震监测系统的监测结果，分析了工作面推进速度、断层、向斜及刀把型煤柱对微震活动的影响，结果表明：微震活动频次与推进度成正相关，推进度的剧烈变化会导致大能量事件的增多；7110工作面微震事件的分布受断层等构造影响较大。通过对微震能量分布的分析划定了高冲击危险区域，进而对田陈煤矿冲击地压的防治提供了依据。
根據田陳煤礦微震鑑測繫統的鑑測結果，分析瞭工作麵推進速度、斷層、嚮斜及刀把型煤柱對微震活動的影響，結果錶明：微震活動頻次與推進度成正相關，推進度的劇烈變化會導緻大能量事件的增多；7110工作麵微震事件的分佈受斷層等構造影響較大。通過對微震能量分佈的分析劃定瞭高遲擊危險區域，進而對田陳煤礦遲擊地壓的防治提供瞭依據。

On the basis of observation data from micro-seismic monitoring in Tianchen Colliery , the influence of mining speed , fault, syncline and hilt-shape coal-pillar on micro-seismic was analyzed.Results showed that micro-seismic number was positive correlated with mining speed and large mining speed variation could result into increasing of matters with large -energy.Micro-seismic matters dis-tribution of 7110 mining face was influenced mainly by fault tectonic .By analyzing micro-seismic energy distribution , high rock-burst danger region was obtained , which provided reference for rock-burst prevention in Tianchen Colliery .
